    If you have a Flex or ATP firewall is this necessary?

    Hi @Pook


    The design for Zyxel CNP or CNP+ is to provide a secure and reliable wireless access for clients.

    CNP mainly provides IP Reputation Filter and CNP+ provides not only IP Reputation Filter but also Wireless Application & Optimization.


    If there is a FLEX or ATP in place, the appliance will inspect client traffic passing through the appliance, if there is malicious traffic, the FLEX or ATP will block it.

    The CNP service targets at SB or PRO users who have no Zyxel USG Flex or ATP at front, typically only have an operator’s xDSL router or a consumer-grade router at front and there is not security features on that router. Though SB or PRO customers do not have a security appliance in place, this doesn’t mean they have no need for secure and trustworthy wireless access. This is where Zyxel CNP can help on.


    For CNP+, the design for Wireless Application & Optimization is focus on application visibility instead of blocking specific applications. CNP+ also provide bandwidth limit by application category.

    The goal is to ensure a smooth and reliable wireless performance for crucial applications at SB or PRO user end.


    In addition, when the AP throttles application bandwidth and inspects malicious traffic at edge, it provides an additional tier of protection at edge for wireless users, meanwhile also offloads the loading of security appliance at front.


    Another use case for CNP/CNP+ is Work from Home scenario.

    For the traffic tunnelling back to the office’s a USG Flex or ATP, for sure the security application will inspect the traffic, but it cannot inspect local forwarding traffic of a SSID at Remote.

    This is where Zyxel CNP/CNP+ can help to provide an additional layer of protection for WFH scenario.  


    In short, there is no conflict for CNP/CNP+ co-exist with a USG Flex or ATP.

    Friendly reminder that models supported CNP+ are:

    NWA110/210AX, WAX510D/610D/630S/650S with V6.30 firmware.

    And CNP supports on NWA1123-ACv3, WAC500, WAC500H with V6.30 firmware.


    Thank you
